The broadnose sevengill shark, Notorynchus cepedianus, is the only extant member of the genus Notorynchus in the Hexanchidae family and is recognizable because of its 7 gill slits, while most shark species have 5 gill slits (with the exception of its larger relative the bluntnose sixgill shark).
The shark is gray or brownish with spots, and its top jaw has jagged cusped teeth and the bottom comb shaped. This adaptation allows the shark to eat sharks, rays, fish, seals, and carrion. The sharks live in temperate areas up to 135 m (450 ft) deep and have only attacked humans in captivity. This shark is ovoviviparous, bearing live young.
